What are the Cisco Umbrella Block Page IP Addresses?

Overview

When a page is blocked by the Cisco Umbrella service, our DNS resolvers display a block page instead of the page with the blocked content. These block pages are served from Cisco Umbrella servers. The anycast IP address and associated block type for these servers are outlined in the table below.

Note:

We do not expect these IPs to change again in the near future, but if they did change, that update would be included in this article.
